No support for sequences in xsd2code

[GoogleCodeExporter]

sequences are handled as a set of elements rather than a sequence.
consider the following xsd:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:element name="pets">
  <xs:complexType>
    <xs:sequence minOccurs="1" maxOccurs="2">
      <xs:element name="dog" type="xs:string" minOccurs="3" maxOccurs="3"/>
      <xs:element name="cat" type="xs:string"  minOccurs="0" maxOccurs="4"/>
    </xs:sequence>
  </xs:complexType>
</xs:element> 
</xs:schema>

this means there is always 1 or two sequences of dogs and optional cats,
each sequence consists of exactly 3 dogs and 0-4 cats. 

e.g.

<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2006 sp2 U (http://www.altova.com)-->
<pets xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="U:\Software\ivef-sdk\ivef-def\branches\IVEF_1_0_0
_DEV\specs\Untitled2.xsd">
    <dog>String</dog>
    <dog>String</dog>
    <dog>String</dog>
    <cat>String</cat>
    <cat>String</cat>
    <cat>String</cat>
    <cat>String</cat>
</pets>

is one sequence, and below are two

<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2006 sp2 U (http://www.altova.com)-->
<pets xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="U:\Software\ivef-sdk\ivef-def\branches\IVEF_1_0_0
_DEV\specs\Untitled2.xsd">
    <dog>String</dog>
    <dog>String</dog>
    <dog>String</dog>
    <cat>String</cat>
    <cat>String</cat>
    <cat>String</cat>
    <cat>String</cat>
    <dog>String</dog>
    <dog>String</dog>
    <dog>String</dog>
</pets>
